Answer:
The dissociation of is as follows.
Explanation:
<u>Molecular equation:</u>
In a molecular equation, reactants are present in the molecular form rather than ionic form.
<u>Complete ionic equation:</u>
An ionic equation shows the complete ions in the solution.
<u>Net ionic equation:</u>
A reaction shows only those ions are participating in the reaction.
The dissociation of is as follows.
.
Answer:
H
hydrogen have different properties
Answer:
CO2
Explanation:
It is Carbon Dioxide that has its carbon atom covalently bound to 2 oxygen atoms.
The fire triangle is composed of
1) heat
2) fuel
3) oxidizing agent (oxygen)
Types of fire extinguishers:
1) Water and Foam - <span> extinguish the fire by taking away the </span>heat<span> element of the fire triangle. Foam agents separate the </span>oxygen<span> element from the other elements.</span>
2) Carbon dioxide - <span>extinguish fire by taking away the </span>oxygen<span> element of the fire triangle and also be removing the </span>heat<span> with a very cold discharge.</span>
3) Dry Chemical - <span>extinguish the fire primarily by interrupting the </span>chemical reaction<span> of the fire triangle.</span>
4) Wet Chemical - <span>extinguishes the fire by removing the heat of the fire triangle and prevents re-ignition by creating a barrier between the </span>oxygen<span> and </span>fuel<span> elements</span>
5) Clean Agent - <span>extinguish the fire by interrupting the </span>chemical reaction<span> of the fire triangle</span>
6) Dry Powder - extinguish the fire by separating thefuel<span> from the </span>oxygen<span> element or by removing the </span>heat<span> element of the fire triangle</span>
7) Water Mist - <span>extinguish the fire by taking away the </span>heatelement of the fire triangle
8) Cartridge Operated Dry Chemical - extinguish the fire primarily by interrupting the chemical reaction<span> of the fire triangle</span>
This is a redox reaction.
Cu²⁺ + 2e⁻ = Cu⁰ copper is the oxidizing agent
Fe⁰ - 2e⁻ = Fe²⁺ iron is the reducing agent
